To @ZZ whom t may concern: 1

Beitkn'own that I, JULIUs HELLWIG, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of- Pennsylvania, have invented a certain newv and useful Improvement in Mechanical Movef ments, of which the following is a specification.

My invention relates to a new and useful improvement in mechanical movements, and has for its object to provide a movement wherein a reciprocating motion will be made to transmit a revolving motion to a shaft, said shaft adapted to be revolved in the same direction upon both the backward and forward movement of the reciprocating portion.

IVith these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order Athat those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now-be described in detail, referring to the accompanying drawings, forming a part of this specification, in which- Figure l is a side elevation of mechanism illustrating my invention; Fig. 2a similarl view to Fig. l, showing the reciprocating por-v tion moving in the opposite direction to that in Fig. l.

In the drawings, A represents a shaft adapted to be revolved, and this shaft is journaled in suitable bearings located in the stationary framework B. Secured upon the shaft Ais a ratchet-wheel C, the teeth of which may be slightly undercut, if desired.

D represents a reciprocating framework which carries two chains Eand F, secured at each end to said framework. The chain E passes above the ratchet-wheel C and the chain F below.

G and H are rollers journaled to the framework B for the purpose of holding the chains in contact with the ratchet-wheel C. p

In Fig. l l have illustrateda reciprocating frameworky as traveling to the left in the direction of the arrow, and it will be seen that the chain F. will thus engage the ratchetwheel C to revolve the shaft A in the directionV of the arrow. The chain F will be loose underneath the ratchet-wheel and slip easily over the teeth'of the ratchet-wheel; but as soon asV the reciprocating framework has reached the limit of its motion in that direction and begins to return in the direction shown by the arrow in Fig. 2 the chain F will then become taut and engage the teeth of the ratchet-wheel C underneath, which will still revolve the shaft in the same direction, and the chain E will then slip over the bevel of the teeth in the ratchet-wheel C, and thus a continuous revolution will be imparted to the shaft A in the same direction upon both the backward and forward movement of the chains E and F.

I illustrates a iy-wheel secured upon the shaft A.

I have shown no particular means for reciprocating the frame D, as that forms no part bfmy invention, and it will be obvious that Ihave illustrated my invention in its simplest possible form, as I do not Vwish to limit myself to the details of construction, but simply wish to claim the broad idea of imparting motion kin the same direction to a 'revolving member by means of reciprocating chains workin g in conjunction with airatchetwheel.

Having thus fully described my invention, whatI claim is l. In a device of the character described, a shaft journaled in stationary bearings, a ratchet-wheel secured to the shaft, a reciprocating framework, two chains secured at each end to said framework, one chain passing above the ratchet-wheel and the other chain below the ratchet-wheel,and rollers j ournaled in stationary bearings in contact with the chains for the purpose of holding said chains in contact with the ratchet-wheel, substantially as and for the purpose specified.

2. In a device of the character described, a revolving member journaled in stationary bearings,.a ratchet-wheel l'carried by said revolving memberga reciprocating member, two chains carried by said'reciprocatingsmember, one chain passing above and the other below the ratchet-wheel,and rollers j ournaled in stationary bearings, said rollers adapted to act 'upon said chains so as to keep the IOC) chain which is actuating the ratchet-Wheel in I chains are traveling in the opposite direction, Contact with said ratchet-wheel, as and for and means for holding the chain acting upon the purpose specified. the ratchet-Wheel in contact with the same,

3. In a device ofthe character described, a as and for the purpose specified.

ratchet-Wheel journaied in stationary bear- In testimony whereof I have hereunto afings, two reciprocating chains, one arranged fixed my signature in the presence of two subabove and the other below the ratchet-Wheel, I scribing witnesses.

one chain adapted to act upon the ratchet- Wheel to revolve the same when said chains are traveling in one direction and the other chain adapted to act upon the ratchet-Wheel to revolve it in the same direction when the JULIUS HELLWIG.
